NYC Clean Heat Project - mapping local air pollution

Volume of air saturated each day by PM2.5 particles from heating boilers. This shows buildings that have been converted to less polluting fuels AFTER conversion.


Around 8,000 buildings in New York City have been burning heavy heating oil. These contribute more soot pollution than all cars and trucks on the City’s roads. The NYC Clean Heat program seeks to improve air quality and save lives in New York by eliminating heavy oil use and accelerating the adoption of cleaner fuels.


Carbon Visuals was asked by Clean Heat project partner Environmental Defense Fund to look at ways to visualise the emissions of fine particulate matter (PM2.5) in order to encourage building owners and operators to sign up to the program.


Visualising quantities of particle pollution is not easy. The air that supports the particles plays a part in making them dangerous to health (by itself, a pile of powder is not a threat)! For that reason, we show the volume of air saturated to the legal maximum. The maximum density of PM2.5 pollution averaged over an annual period: 15 μg/m3.
